NO IMPACT TO PFA FROM CORONAVIRUS (COVID-19):

As a Made in USA manufacturer, only occasional items not available domestically are used in PFA products. Currently, PFA has large inventories of all components to support our off-the-shelf cylinder deliveries (5-7 business days). We anticipate no impact to our supply chain or our ability to supply products within typical lead times.

KOR-LOK Side Action Systems KOR-LOK® KOR-LOK® Side Action Systems (core pull & locking cylinders) are for preloading and locking movable cores on injection molds and die cast dies, providing improved part quality, cycle speed, and smaller mold/smaller press capability.

KOR-LOK® Side Action Systems
Preloading and Locking Core Pull Cylinders specifically designed for Injection Molds. Zero Flash Molded Parts on the First Shot! There is only one KOR-LOK® - if you're not talking to PFA you're not getting a KOR-LOK®. With 100% preload at ZERO pressure and fast Delivery on ANY STROKE size, you are just learning about what KOR-LOK can do for you.
Hydra-Jaws Quick Mold Change (QMC)
PFA's Quick Mold Change plates and Quick Knock-Out systems can be used together or separately to provide rapid mold change capability with the confidence of hydraulic clamping force and true mechanical clamp holding.  The unique slot design supports changeover from top/bottom to right/left clamping or any combination desired.  Once clamped, mechanical locks hold the mold secure without hydraulic pressure.
Quick Die Change (QDC)
From PFA's unique portable Mechanical Die Lifters and spring loaded lifters to high force hydraulic clamping and lifting systems, you'll find the items to build a system to meet your needs at a price you can afford.  QDC systems speed up production, keep presses running, and make die changes simple and efficient.  Proven systems that have excellent ROI and increase employee satisfaction are a win/win for everyone.
SWITCHMAX® Connectivity Cables
More than simply cables, PFA's NEW SWITCHMAX® connectivity solution, originally designed to connect multiple side-action mold cylinder sensors in series for easy "plug and play" connections machine inputs, SWITCHMAX® now offers cross connected sensor verification, PNP and Relay sensor connections, relay power adaptors for AC and zero volt inputs, and much more. Systems are now often used without cylinders for customized sensing of mold actions and integrating rocker and plunger switches.

Self-Locking and Braking Cylinders
Self-Locking Cylinders function with common standard cylinder two port activation, but provide locking and holding forces up to 10 times more than a standard cylinder of the same bore size. Braking cylinders are less aggressive for holding force, but employ an internal to rod brake that allows holding loads at any location in the stroke.
Modular End-of-Arm Automation (EOAT)
With some of the highest force to weight ratio Grippers, PFA really does GRIP IT! And that's not all - we have Compliance Devices and Flexible Wrist Overload Protection (OPD's) for a complete modular EOAT solution. Don't forget to check out our popular GRIPPER PADS with fused metal (steel and aluminum) backing for applications ranging from heavy industry to human interacting collaborative robots (Cobots)!
